On the back of the caliper there should be a bolt its a 14mm you take it out and inside there is a bolt also its Allen key you use and Allen key and retract the caliper. it works on all 626 from 1994 till 2002
There is a 14 mm bolt on back of caliper. Remove this & use a 4 mm Allen wrench to back piston into caliper.
The caliper piston may not retract properly due to a lack of lubrication, a damaged seal, or air trapped in the brake system.
The Brake Piston Cube is a cube-shaped tool used to retract brake caliper pistons in vehicles when changing brake pads. Its design allows it to fit into the caliper housing and apply even pressure to retract the pistons back into the caliper, facilitating easier brake pad replacement. By turning the Brake Piston Cube, the pistons are compressed uniformly without damaging the caliper or seals.
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
Clockwise to retract piston into caliper body
The brake caliper may not retract properly due to issues such as a stuck piston, worn out seals, or debris buildup. These issues can prevent the caliper from releasing pressure on the brake pads, leading to brake drag and reduced braking performance.
You cant, it needs a 'C' clamp.
Rotor "Out of Round" when rotating "High" spot will cause piston to retract into caliper body

To retract the brake caliper piston on a G20 Infiniti, you'll need a brake caliper tool or a C-clamp. First, remove the caliper from the rotor by unbolting it, then position the tool or C-clamp over the caliper piston and gently turn or squeeze to push the piston back into the caliper housing. Ensure you do this slowly to avoid damaging the piston or seals. Finally, reassemble the caliper and check brake fluid levels before testing the brakes.
To retract a caliper, first, ensure the brake system is depressurized if you're working on a brake caliper. Use a caliper tool or a C-clamp to gently push the piston back into the caliper housing. If the caliper has a screw-type mechanism, turn the screw clockwise until the piston is fully retracted. Once retracted, check for smooth movement and reassemble any components as needed.
